Savior

The Savior (appearing in DMC4)is a giant demon which is brought to life when Sanctus unites the blood of Sparda (in this case Nero) with a maiden (Kyrie). It resembles Sparda to an extent but is completely made of stone except for a few large sapphires which are its only vulnerable spots. After absorbing Nero and Kyrie into the Savior, Sanctus retreats into his divine creation and flies off using its power to destroy demons which he released into the human world inorder to regain the faith of local people. With Nero locked away within the savior it is up to Dante to take it down. This battle takes the whole of Mission 18. Despite his awesome style and skill, Dante is unable to take down the savior but manges to send Yamato through the central sapphire of the Savior and breaking the chamber in which Nero is being held captive. Nero retrives Yamato and proceeds through the insides of the savior until he reaches Sanctus who has gone under his intiation and become "Sanctus Diabolica." Nero defeats Sanctus, saves Kyrie and retrives the weapon Sparda before bursting out of the central sapphire on the savior. However, the savior (although no longer as powerful as before after the destruction of Sanctus)goes on a destructive rampage. Nero uses his devil bringer arm to bring it down ending the game.

It is interesting to note that at the end of Mission 20 when Nero confronts the savior, it appears to have a beard whilst beforee it was clean shaven.
